The significance of systematic and intensive plastic parts inspection processes can never be overemphasized given the possible consequences when a non-conforming product is released into the market.
InTouch employs the most recent international standards in developing its plastic parts inspection and quality control protocols. The following are a few of the most current international standards for molding compound parts:
Material Inspection
Raw material, packaging material, and product component is verified for authenticity and is thoroughly inspected for composition. During production, the use of genuine materials is strictly monitored.
Visual Inspection
In the case of plastic gears, a representative sample is drawn. These plastic parts are then thoroughly cleaned and visually inspected for cracks, pits, chips, warping, shrinkage, and other deformities.
Plastic parts that have been manufactured by injection molding will need to be visually inspecteded for sink marks, gas and burn marks, flash or plastic leaks, short shots and knit or weld lines.
Functional Inspection
Plastic parts are inexpensive, easily-produced, corrosion-resistant, and lightweight. Inherent weak points, however, include susceptibility to shrinkage, expansion, warping, and structural damage, especially when subject to a degree of heat and pressure.
Plastic gears are tested for abrasive wear, normal wear, corrosion resistance, heat resistance, load capacity and performance under high speed applications. Special attention is given to tooth geometry as it is the focal point of plastic gear inspection processes. Internationally-practiced tolerancing standards are followed before passing the conformance and non-conformance conclusion.
